greatest invention in history

Thousands of years ago in ancient Egypt, people built pyramids for the Pharoah. At that time there were no machines, so how could they move such huge stones? How could they create such splendid pyramids? How could they create such a miracle? The answer, of course, is the wheel. The wheel makes everything possible.

The common uses of the wheel are obvious. Rather than travel on foot or on horse, we have learned to travel by horse-drawn carriages, cars, trains and now airplanes and rockets. The Industrial Revolution could never have occurred without the wheel. Not only do industrial machines, such as we find in factories, or home appliances such as washing machines and air conditioners, depend on the wheel, even the printing press that brought learning to the masses depended on gears - toothed wheels! - to work. In other words, though the printing press was important, it simply couldn't exist without the wheel.

The computer chip also would not be the useful device it is, without the help of the wheel. The computer chip itself may not use a wheel or gear directly, but peripheral devices such as printers and disk drives do. Without the wheel, we could in theory have a powerful computing device. However, we wouldn't be able to save our work or show it to other people! Without the invention of the wheel, the computer would be next to useless.

So, can you imagine a world without the wheel? Can you imagine a world without long distance travel? Can you imagine a world without a printing press to communicate the best writing in the world? Can you imagine a world with no useful computers? Everything that came after the wheel, and everything that is to come, depends on the greatest invention in history. The wheel!
